Steinberg ur22 mk2 question...RESOLVED.

I need a powered hub to use my iPad Pro with a .Kawai VPC1 controller. First I was considering the IRig Pro I/O but saw recs for the Steinberg AI. Watching a review of the ur22 mk2 it seemed like they were saying the headphone out only gives a mono signal! Is that True, or were they talking about the knob that adjusted the hp mix?

Also, do you think this will solve the problem (just the iPad prompted a "device does not have enough power" pop up) to get the Kawai working? I like the Steinberg better for build and functionality... anything to recommend the IRig?

Also, I will need to get a power brick for either and not certain if I can get that in Turkey.
Help! Thanks!

Headphone output is mono if you are using it as a reference guide, not connected to the ipad. For example i wanted to use it to commect my guitar amp sim and stereo fx pedals without my ipad, but you lose stereo. Once you connect an ipad/computer you get full stereo.

Digital audio will be monitored in stereo but analogue inputs via L and R will be monitored mono (even though actual Digital output will be stereo). This configuration is kind of helpful if you were say using a guitar in L and mic in R. With powered hub you can Power your keyboard, iPad and Steinburg and will have no problem getting stereo headphone monitoring.

Also you can choose input 1&2 as a sinle stereo pair or as separate mono channels in any app that lets you select inputs

I saw the UR today and had to walk a mile in the music section of Istanbul to get a 5v charger. ( Turkey!) But when I tried the Kawai VPC1 the action was way too sluggish and heavy for me, so I got an MP11 instead which runs an iPad without an AI, no problem. But thanks, as always.

@TrevorLlewellyn it was a two month ordeal but I really love the Kawai. Worth the Byzantine struggle... Famous last words in Turkey... "No Problem!"
